UNITED STATES PATENT Ormea! A. UUTLER AND E. S. YRIGHT, OF NEV YORK, N. Y.A

IMPROVED CARPET BEATE'R AND CLEANER.

To all whom it nfl/ay concern:

Be it known that we, A. CUTLER and E. S. WRIGHT, both of the city, county, and State of New York, have invented certain new and useful Improvements in Carpet-Sweeping Machines; and we do hereby declare that the following is a full, clear, and exact description thereof, reference heilig had to the accompanying drawings, forming a part lof this specification, in which#- l Figure l is a vertical longitudinal section taken through our machine, showing clearly the manner of whipping or beating the carpet as it passes through the same, and also the arrangement of blast and suction pipes for conducting or drawing the dust from the beating-box both above and below the carpet. Fig. 2 is a transverse vertical section taken through Fig. l, as indicated by the red line afm marked thereon. This section shows clearly the suction-pipe leading from below the carpet to the rear fan-box, and it also shows a front view of the rotary elastic beaters.

Similar letters of reference indicate corresponding parts in both hgureS.

To enable those skilled in the art to fully understand our invention, we will proceed to describe its construction and operation.

In the drawings, A represents the framing of the machine, which may be of any suitable width, in the extreme front and rear ends of which are baud-rollers B B, over which pass any required number of endless bands d, which are furnished with hooks or clamps or any device by which the carpet may be readily secured to them during its passage through the machine to be cleaned. These rollers or cylinders move in the same direction, and in that direction indicated by the arrows in Fig. 1, and they receive their motion from the main driving-shaft C, through the medium of driving-belts and pulleys. When the carpet to be cleaned is attached to the endless bands a, and the machine is set in motion, it is conducted over a suction-box D, situated inter! mediate between the rollers, the mouth of which is on a plane with the upper surface of the rollers. This box `D contains rotary beaters, all of which are attached to the shaft E, which is driven in the direction of the arrows, Fig. 1, by a belt b, from the main shaft C. These beaters, which will be hereinafter described, act with great rapidity against the carpetand beat the dust and dirt from it both above and below the carpet. Above the carpet is a box D', and between these two boxes the carpet is passed to be beaten and cleaned, as clearly represented by Fig. l of the drawings.

The objectof submitting the carpet to the beating operation between the boxes D D is to prevent the dust from escaping into the room, which to do this is a great desideratnm in carpet-cleaning machines, for the consequence of shaking or beating a very dusty carpet without Vsome provision to allay the dust can well be imagined. Besides, the carpet after it passes through the machine and comes out clean is very soon filled with dust again. Therefore to obviate this difculty we com bine with the beaters employed to free the carpet of its dust a system of blast and suction pipes for conducting the dust away from the boxes D D as fast as it is free from the carpet. These currents of air not only serve to carry the dust off but they serve au important object in assisting the beaters or whipping-boardsto separate the dust from the carpet. For this purpose the drawings show an arrangement of blast and suction pipes combined with the beaters in thelower box D. l To create these currents are arranged over the boxes l) D two fan-compartments G G', with rotary fans ll Il', both of which turn in the same direction; but the fan H draws the dust from box D and from below the carpet, through a vertical pipe or pipes J, (shown clearly in Fig 2,) into the fan-box G, from which it is discharged through spout K and conducted to any desirable place. Should it be found necessary, a short suction-pipe (not shown in the drawings) may lead from the upper box D above the carpet to the main suction-pipe J. This,- with the main pipe, would draw thefdust directly from above and below the carpet into the fan-box G. The fanbox G', with the fan H and airopening in the side of the box, serves to furnish strong blasts of air both above and below the carpet. For this purpose the inclined blast-pipe M leads from the bottom of this box G into the upper box D. The mouth of this pipe or spout is brought very near to the surface of the carpet, so that with a very strong blast it arjen assists n'iat'erially in separating the dust from the carpet. The blast-pipe N is arranged under the carpet in the saine manner as pipe M is above it. The direction of the currents of air and dust through the various pipes is represented by arrows in the drawings. The dust `raised above the carpet by the combined action of the beaters and the blast is conducted down on each side of the carpet int-o the lower box D, from which it will be drawn through the suction-pipe J; but it the short suction-pipe is used, as above described, the dust Will be drawn directly from box D. This latter arrangement is preferable.

The device for beating the carpet is important, as it combines eiicieucy of action with compactness. It is by farpreferable to the vibrating sticks or Whips, for the beatingr` arms can be made to strike the carpet in uniform and rapid succession as the carpet moves through the machine. These whips a. consist of curved elastic arms with rounded ends or with a piece of wood secured to their ends, as shown by the drawings. These arms are all secured to the shaft E andare bentin the form of parabolic curves. Their motions are in the direction of the arrows, Fig. l, and their sha-pe gives them sufficient elasticity to prevent injury to the carpet When they are Y rotated with great rapidity. These rotary beaters themselves create a current of air in the box D, which assists indispelling the dustl. The employment of the parabolic spring,

beaters a', when the same are elastic throughout their entire lengths and are arranged upon a driving-shaft E, substantially as herein shown and described, for the purpose set forth.
